Bad Gateway after CDD QA Upgrade

Products

• Continuous Delivery Director

Issue/Introduction

After upgrading the CDD QA server from 6.9 to 8.2, the CDD Server/URL was not responsive. Trying to load the load balanced URL would just sit there spinning until it finally received:

Bad Gateway

Processing of this request was delegated to a server that is not functioning properly.

 

 

Environment

Release : 8.2

Component : CONTINUOUS DELIVERY DIRECTOR

 

Cause

In the Tomcat8.5\logs\tomcat8-stderr.2021-06-15.log we found the following messages:

... Unexpected death of background thread [ContainerBackgroundProcessor[StandardEngine[Catalina]]]

java.lang.OutOfMemoryError: Java heap space

 

Resolution

Add more memory to Tomcat. To do this we followed these steps:

• Stop Tomcat.
• Run tomcat_install/bin/Tomcat8w.exe and change the following values from the Java tab:
  • Initial memory pool: 2048
  • Maximum memory pool: 4096
• Start Tomcat.
